BUTTON AND BUTTON-FASTENING.

SPECIFICATION forming part of Letters Patent No. 311,eeo, dated February 3, 1885.

Application filed June 12, 1884. (No model.)

To aZZ whom, it may concern.-

Be it known that 1, WILLIAM J. ALLASON, of Billings, in the county of Yellowstone and Territory of Montana, have invented a new and useful Improvement in Buttons and Button-Fastenings, of which the following is afull, clear, and exact description.

The invention relates to the description of buttons which comprise a rivet or shank piece having a small head or protuberance on its outer end, which, together with the shank, is projected through the cloth or other material the button is designed to be secured to, an enlarged head or flange on its inner or back end, and a button or button-body composed in part of a perforated back piece or plate, through which the outer small head and shank of the rivet pass after projection through the cloth, and, in part, of an open-eyed and radially-slitted plate arranged to engage peripherally with the back piece of the body and to snap and fit at its center,where radially slitted, into anotch or reduction in the shank at back of the small or outer head of the rivet.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 represents a mainly sectional transverse view, upon an enlarged scale, of a button embodying my invention and as secured to a piece of cloth or other material; and Fig. 2, a top View of the button or button-body before it is secured.

A is the shank or stem having a small outer head, a, formed by a notch or reduction, I), in the shank, and having a flange or plate, 0, at its back or inner end. This shank or stem piece, which thus resembles a rivet, may be made of metal or any other suitable material, and when applied to fasten a button it is projected, with its head a foremost, through a hole in the cloth or material 13, and so that its flange c is free to rest against the inner or opposite side of the cloth to that from which the shank projects.

O is the back piece or portion of the button or button-body, and D its front plate or portion. The back piece or bent disk, 0, may be made of rubber, bone, or other material, and has an eye or hole, d, in its center large enough to allow of it freely passing over the head a and body of the shank A when fitting the button to its place, as shown in Fig. 1, and of a certain amount of play to provide for inclining or giving flexibility to the button, if necessary. The front plate, D, of the button or button-body is made of metal, with a bulge or swell, e, inits cent-er, through which is a hole, f, corresponding in size to the not-ch or reduction, 12, in the shank, andhavingthree or more slits, g, extending outward from said hole. These slitted portions snap or fit into the notched portion 1) of the shank, back of the head a, when the button is fitted to its place, and serve to securely hold the button from becoming detached. The outer edge of the plate D is fitted to permanently engage with the back plate or piece, 0, by entering within the bent-over edge of said piece 0, or otherwise. This forms a very simple and easily-applied button-fastening, which is both secure and durable. The button may vary in style as desired, and its head, if required, be altogether coveredlike a brass army button, for instanceto conceal its mode of fastening and to give it a certain ornamental appearance.

I am aware that a button having a headed shank which is adapted to be sprung through a perforated and radially-slitted spring-disk has been used, and I do not claim such construction, broadly.

My invention is distinguished from others of its class in that the spring-disk and headed shank are so formed as to serve as an orna mental front for the button. To this end the head is made large in proportion to the size of the button, and is of a hemispherical form, while the spring-disk, in order to give it sufficient elasticity to admit the head, is made with a hemispherical bulge or swell, e, which adds to the ornamental appearance of the button. Apart from ornamentation, this construction has the advantage of allowing the spring-disk to be strongly secured and braced against strain by having its edge overlapped by the edge of the button-back.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the radially slitted spring-disk and button-front having the hemi- 5 spherical bulge e at the center, the buttonback having its edge overlapping the edge of said disk to hold it securely against strain, and the shank having a comparatively large hemispherical head adapted to be sprung through the perforation in the disk, substan- 1o tially as shown and described, whereby the spring-disk is made to form an ornamental and strong front for the button.

WILLIAM J. ALLASON.
